Review on Premium Quality Pet Heroic Dog DoorBells for Potty Training & House Training, Unique Style, Adjustable Length for Small, Medium and Large Dogs – Loud, Crisp, and SEO-Friendly DoorBells by Stacy Sturm

I have a Saint Bernard puppy and we bought this bell hoping to use it for potty training, honestly I doubt it would work. Spoiler alert IT REALLY FOUND IT! It was very easy to teach her how to use the bell, just ring before you open the door and then show her that she can tap her nose on it and give her a treat. It only took a few times before she started doing it herself. Now she does it every time she wants to go somewhere, even if she just wants to go out and play every 5 minutes 🤣. An added bonus is that it won't scratch the door, and as it's going to get really big one day, that's a huge plus! Now she is fully potty trained but we will keep this bell forever!
